--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> 2011-07-12 07:32:35 UTC ---
Slightly reduced testcase for -O3 -funroll-loops:

int a, b, c, d;

static void
foo (int *x)
{
  c = 0;
  while (1)
    {
      if (*x)
break;
      while (b)
for (; c; c = 0);
      for (d = 18; d != 18; d++)
if (c)
  {
    foo (x);
    return;
  }
    }
}

static void
bar ()
{
  foo (0);
  foo (0);
  for (;;)
    ;
}

baz ()
{
  for (; a;)
    bar ();
}

ICEs in fix_bb_placements during rtl loop peeling.
